Keypad calls for help on drives
Control Panel/Keypad
The control panel/keypad on the ACS550 low-voltage AC drive resembles a cellphone, from the way screens pop up to the Help key. It has separate Start and Stop keys; parameter set keys that use arrows for incremental up or down sets; and two soft keys, the functions of which change according to the operating state of the panel. A built-in Help button, start-up assistant, maintenance triggers, diagnostic assistant and a real-time clock assist in operator setup and use.
